Check Specialized website. There seems to be 2 different versions of this wheelset and one version has a proprietary 142 width hub that can't be converted, the other version can be either QR or through axle.

If the wheels are the 142+ version you are out of luck. If they are the regular SL's you just switch the end caps.
